I think that we need to see the full truss output from when the user and from
when root attempts this :-( Any user can
redirect to /dev/null without hindrance AFAIK. In certain situations, I guess
that you might get EROFS somewhere along
the line; but as you say, if root can do it, then its not that...
I have seen something like this before, but darned if I can remember in what
circumstances... :-(
